In order to achieve the above object, the present utility model adopts the following technical scheme:
the utility model provides a cylinder body oilhole and idler optimize structure which characterized in that: comprises a cylinder body and an idler wheel; an idler wheel mounting position is arranged in the cylinder gear chamber, a main oil hole is formed in the idler wheel mounting position, and an oil guide groove is formed in the main oil hole; the left part of the idler wheel is a positioning block, the right part of the idler wheel is a gear shaft, a boss extends from the edge of the positioning block, lubricating oil holes are formed in two sides of the center of the gear shaft, and the lubricating oil holes are directly formed in the left end of the positioning block; the idler wheel is arranged on the idler wheel mounting position through a positioning block, and the lubricating oil hole is communicated with the oil guide groove; the boss covers the main oil hole.
Further, three mounting holes are formed in the idler mounting position and the idler center, and the three mounting holes are distributed in a triangular mode.
Further, a positioning column is arranged in the center of the left end of the positioning block, a positioning hole is formed in the center of the idler wheel installation position, and the positioning column is matched with the positioning hole.
Further, the oil guiding groove is formed in the center direction of the idler wheel installation position.
Compared with the prior art, the utility model has the advantages that:
according to the utility model, the oil hole of the idler wheel installation position in the gear chamber is provided with the oil guide groove, the oil guide groove is arranged towards the center direction of the idler wheel installation position and is used for communicating the idler wheel with the lubricating oil hole on the idler wheel, which is smaller in size, so that the size of the idler wheel is reduced, and meanwhile, the boss extends at the edge of the positioning block of the idler wheel to block the main oil hole on the idler wheel installation position, thereby realizing the optimization of the oil duct. According to the utility model, through a cylinder body slotting mode, under the condition that the position of the main oil hole is not changed on the basis of the original engine, the idler wheel with smaller size and smaller weight is matched, and the light weight design is realized.
